Why Poland is "surprised" by winter and snow every year? [192]
A bit about tyres...
On a nice sunny day on good asphalt the best tyre to have is one with a medium compound and very little in the way of tread...Many people think that a lack of tread means a lack of grip , but not so , a bald tyre works very well on a smooth dry road , not so well in the wet of course...Look at the old formula one cars , they had slick tyres , because thats what gives the most grip...
Of course they pull in and change tyres if it starts to rain , as a slick tyre is not good in the wet , a tyre with a tread is needed , the tread is what stops the water from building up under the tyre and causing aquaplanning this is the scarey moment when your tyres leave the road surface and ski along on the water , braking and steering does not work...!
For a road tyre you need a tyre that works well in the dry and the wet , and also one that is not going to wear out too quickly , when it comes to tyre compounds the softer the tyre the more grip it gives , but of course the softer tyre is going to wear out much quicker...
When it comes to snow you need not only a good tyre tread , but one where the tread is more widely spaced and agressive , this is not only to get a grip on the snow , but to stop the treads filling up with snow , if this happens they are no better than a slick...
I don,t change tyres on my car because its a 4 x 4 Jeep and has tyres that are made to cope with mud , any tyre that can grip in mud will be good in snow , the more agressive the tread the better the grip , but the down side is that such tyres are quite noisy when you are on clear tarmac....
The worst tyres to have on snow are the low profile tyres fitted to high performance cars , these are all but useless on snow , and its best to leave the car at home if the snow is coming down hard...for this type of car winter tyres are essential...
once the snow turns to ice it does not matter what tyre you have on...it won,t grip unless you have metal studs in it...
